    • A quad flat non-leaded package including a first patterned conductive layer, a second patterned conductive layer, a chip, bonding wires and a molding compound is provided. The first patterned conductive layer defines a first space, and the second patterned conductive layer defines a second space, wherein the first space overlaps the second space and a part of the second patterned conductive layer surrounding the second space. The chip is disposed on the second patterned conductive layer. The bonding wires are connected between the chip and the second patterned conductive layer. The molding compound encapsulates the second patterned conductive layers, the chip and the bonding wires. In addition, a method of manufacturing a quad flat non-leaded package is also provided.
    • 提供了包括第一图案化导电层,第二图案化导电层,芯片,接合线和模制化合物的四边形扁平非引线封装。 第一图案化导电层限定第一空间,并且第二图案化导电层限定第二空间,其中第一空间与第二空间重叠,并且第二图案化导电层的一部分围绕第二空间。 芯片设置在第二图案化导电层上。 接合线连接在芯片和第二图案化导电层之间。 模制化合物封装第二图案化导电层,芯片和接合线。 此外,还提供了制造四边形非铅包装的方法。
